the presence of catalytic amounts of molecular iodine and stoichiometric potassium persulfate, a green, highly chemoselective, regioselective and cis-selective radical isothiocyano-chalcogenization of alkenes with NH4SCN in water is disclosed. This three component reaction features high selectivities, an environmentally benign process, mild conditions, high yields, excellent functional-group tolerance

A simple and efficient catalyst‐free method for isothiocyanatoalkylthiation of styrenes has been developed. The protocol uses (alkylthio)pyrrolidine‐2,5‐diones and trimethylsilyl isothiocyanate as the isothiocyanatoalkylthiolating reagents, dimethylformamide (DMF) as the solvent, and the reactions were completed within one hour with tolerance of some functional groups. No catalyst and additive were

A new method for the synthesis of thiocyanato- and isothiocyanatoalkyl phenyl sulfides by the reaction of unsaturated compounds with ethyl benzenesulfenate and trimethylsilyl isothiocyanate has been suggested. Regio- and stereoselectivity of the reaction was studied, having taken alkenes, dienes, and alkynes as examples.

generated in situ and arylsulfonylchlorides as electrophiles in water for N-functionalization of bicyclic amidines (DBN and DBU). This strategy provides complementary access to a range of thiouredosulfides, sulfonamides, aroylthioureas and amides derivativatized with distal γ- and ω-lactams. A novel sulfonylchloride mediated formation of β-uredo sulfides has been achieved from β-isothiocyanato sulfides
